APPARATUS FOR CLEANING OIL-WASTE.

, Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed April4, 1906. Serial No. 309,839.

To all whom, it may concern.-

Be it known that I, J A001; 1. ORKIN, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Apparatus forCleaning Oil-lVaste, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to certain improvements in apparatus by which oils,grease, gums, and other substances are extracted from cotton and otherwaste by the application of steam or volatile solvents, the substanceswhen properly extracted being suitable to be used for the same purposeas formerly, and the waste is cleansed and dried for future use.

One object of the invention is to provide a machine of comparably fewparts which will be simplicity itself in operation.

The invention consists in the combination of elements and in certainparts of novel construction entailed in the combination of said elementsto obtain the desired result.

A full understanding of my invention can best be given by a detaileddescription of a preferred construction embodying the various featuresof my invention, and such a de scription will now be given in connectionwith the accompanying drawings, and I obtain my object by the mechanismthere illustrated, showing such preferred construction, and the featuresforming the invention will then be specifically pointed out in theclaims.

In the accompanying drawings, Figure 1 is a central vertical section ofmy improved apparatus for separating oily substances from waste materialand a side elevation of the waste-drier. Fig. 2 is a plan view of myapparatus. Fig. 3 is a cross-section of the separator. Fig. 4 is a sidesectional view of the drying-pan. Fig. 5 is a sectional view on the line5 5 of Fig. 4.

Latitude'is allowed herein as to details, as

- they may be changed or varied at will without departing from thespirit of my invention and the same yet remain intact and be protected.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The tank 6 represents a cylindrical metal receptacle supported by thelegs or standards 7 and supplied with steam from the steam-pipe 8,opening into it near its bottom 9. The tank is provided with thesteam-out-' let pipe 10, which has its entrance just below the cover 14and about diametrically opposite the opening of the steam-pipe 8. Adripcock 12 is provided in the bottom 9 for draining off the ingredientsseparated from the waste material and for the escape of the water usedin washing the waste material, which water is supplied by theservice-pipe 13. The tank 6 is provided with a cover 14, having the ironfacings 15 and 16 at right angles to each other, extending at theirouter ends beyond the rim of the cover 14 and having slots 17 in theirouter ends for receiving the screwlugs 18, pivoted to the iron facings11 of the tank 6 and on which thumb-screws 19 are turned. Within thetank 6 is adapted to be placed a perforated cylindrical pan or can 20,provided with a cover 21, a bottom 22,

having a series of perforations or openings an opening in the center ofthe cover 21 and through an opening in the center of the bottom 22 andturning upon the bearing 27 on the inner side of the bottom 9 of thetank 6. The shaft 25 is provided with a series of arms 28 for agitatingthe waste placed within the can 20. The waste to be treated is placedwithin the pan 20, the covers 21 and 14 and the shaft 25 adjusted, andthe shaft set in motion. The turning of this shaft simultaneously turnsthe arms 28 and the pan 20. Steam is applied through the steam-pipe 8and passes through the perforations 23 24 into the pan and among thewaste material. The oily substances pass from the waste down through theperforations and into the tank 6, where it can be drawn off as desiredthrough the drip-cock 12. If desired, the

ICC

be turned within the pan and agitate the waste material in a morethorough manner.

After steam has been supplied. for a suflicient length of time the steamis shut off, the oily substances are withdrawn, and the tank and pan arepartly filled with water from the service-pipe- 13 and the wastethroughly washed, after which it is withdrawn and placed Within the tray31, which tray has downwardly-extending curved arms 37 for holding itupon the coils of the steam-outlet pipe 10, and which pan is providedwith the openings 32 in its bottom for the escape of water or othermoisture and for the more ready entrance of heat to the waste materialwhich has been placed within the tray to be dried. Extending throughthis tray is a bar 33, provided with rods 34, having downwardextendingprongs 35 to catch the waste material and move it forward and backwardwithin the tray as the bar 33 is carried for-' waste within the tray isagitated by movement of the pulley 26 as the oily waste is agitatedwithin the pan 20. g

It is understood that my invention is not limited to the specificdetails of construction shown in the accompanying drawings, but thatsaid details may be varied in the practical carrying out of myinvention. It is also to be understood that the combinationsspecifically set forth in the several claims are intended to beseparately claimed without limitation to the use in connection therewithof other features and details of construction illustrated.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In apparatus for extracting oily substances fromwaste material, a steam-tank, a pan provided with a perforated bottomwithin the tank for holding the waste material, arms within the pan, asteam-supply pipe having an opening into the tank below the bottom ofthe pan, a steamoutlet pipe for the tank having its opening above thebottom of the pan, and means for simultaneously moving the arms and pan,substantially as shown and described.

2. In a device of the class described, a steam-tank, a perforated panwithin the tank, a shaft extending through the pan and pivoted on thebottom of the tank, arms carried by the shaft, means for revolving theshaft, means for connecting the shaft and pan whereby the pan may berevolved with the shaft, means for supplying steam to the tank below thebottom of the pan, means for Withdrawing the steam from the tank abovethe bottom of the pan, a drip-cock for drawing off the oily substancesfrom the tank, and a water-pipe connected with. the tank above thebottom'of the pan for supplying water as the pan is revolved,substantially as shown and described.

3. In apparatus for extracting oily substances from waste material, incombination with a steam-tank of a pan for holding the material andadapted to be rotated within the tank, a water-pipe adapted to supplywater to the tank and its pan for washing the material after theapplication of steam thereto, a steam-pipe connected with the steamtank,and a perforated tray adapted to be supported upon the steam-pipe fordrying the Waste after washing, substantially as shown.

4. In a machine of the class described, a perforated tray, arms attachedto the tray for supporting the same above a steam-pipe, and means foragitating the contents of the tray, substantially as shown.

5. In a machine of the class described in connection with a coil ofsteam-pipe of a tray having a perforated bottom, means for supportingthe tray upon the coil of pipe and an agitator for the contents of thetray, substantially as shown.

6. In a machine of the class described, a tray provided with a series ofopenings, means for supporting the tray upon a steampipe with itsopenings above the pipe, a bar extending through the tray, rods carriedby the bar provided with downward-extending prongs and means for movingthe bar lengthwise of the tray, substantially as shown.

7. In a machine of the class described, a cylindrical tank, a cover tothe tank, a perforated pan within the tank, a central vertical shaftextending into the tank through the pan and having agitator-arms withinthe pan, means for forcing steam upward through the pan, steam-outletpipes, a water-supply pipe for forcing water downward through the pan, afaucet in the bottom of the tank for the escape of the water, means forconnecting the shaft and pan, rotating means Without the tank andconnected to the shaft for revolving the shaft and pan, a tray, meansfor supporting the tray upon the steam-outlet pipes, an agitator withinthe tray and operated by the shaft, substantially as shown.

In testimony whereof I affiX my signature in presence of two witnesses.

JACOB I. ORKIN.
